It is widely acknowledged that doping of carbon materials by multi-elements with different electronegativities can result in unique electron-donor properties and novel functionalities because of the strong synergistic interaction among the dopant atoms. In this study, boron and nitrogen codoped graphene aerogels (BNGAs) are synthesized and their photocatalytic activity towards decomposition of bisphenol A (BPA) under visible light irradiation is systematically examined. The BPA molecules are rapidly adsorbed onto the 3D interconnected pore system of the BNGAs under dark conditions, and eventually mineralized upon exposure to visible light, indicating the synergy between adsorption-enrichment and photocatalysis during degradation of BPA. Notably, almost 96% of BPA is removed and over 88% of total organic carbon is eliminated by the as-prepared BNGAs. More importantly, the BNGAs can retain approximately 92% of their initial activity even after repeated cycling. In addition, the BNGAs display great potential for the disinfection of harmful pathogens like Escherichia coli, with a photocatalytic decontamination rate of 1.2 × 10³ CFU h⁻¹ g_cat⁻¹. In view of their attractive multi-functional performance, the as-developed BNGAs merit further consideration for eliminating emerging organic contaminants and pathogens from freshwater sources.

广泛公认的是，由于掺杂原子之间的强协同作用，用具有不同电负性的多元素掺杂碳材料可产生独特的电子给体性质和新颖的功能。在这项研究中，合成了硼和氮共掺杂的石墨烯气凝胶（BNGAs），并系统地研究了它们在可见光照射下对双酚A（BPA）分解的光催化活性。BPA分子在黑暗条件下迅速吸附到BNGAs的3D互连孔系统上，并最终在暴露于可见光下矿化，表明BPA降解过程中吸附富集和光催化之间具有协同作用。值得注意的是 所制备的BNGAs去除了几乎96％的BPA，并消除了88％以上的总有机碳。更重要的是，即使反复循环，BNGA仍可以保留其初始活性的约92％。此外，BNGAs还具有消毒有害病原体的巨大潜力，例如大肠杆菌，其光催化去污率为1.2×10 ³ CFU h ^-1 g _cat ^-1。考虑到它们具有吸引力的多功能性能，应进一步考虑从已开发的BNGAs中消除淡水源中新兴的有机污染物和病原体。
